Used to drive a Transit and Ifor Williams trailer with ride on mowers, could never, ever, back it up, Knew all the rules, opposite lock to where you want to end up.
Drive forward to straighten it all up, gently back and the trailer would always end jack knifed into the rear of the transit.
I'm not proud and asked a guy to back it up in our plant yard, he jumped in, un jack knifed it and slotted it in.
He said he used to be in the Army and drove the tank transporters about.
